Femoral shaft fractures are amongst the most common major pediatric injuries treated by orthopaedic surgeons. They represent 1-2% of all fractures in the paediatric population. Paediatric males are affected more commonly than females. [1] There are various methods available for operative stabilization of paediatric femoral shaft fractures, which include external fixation, compression plating and rigid and flexible intramedullary nailing. [2] There is no uniform consensus on the treatment modality for femoral shaft fracture in school-aged children between 6 years to16 years. Titanium elastic nailing system (TENS) is a recent and widely used technique which allows stable reduction, maintenance of reduction and early mobilization. [3] American Academy of Orthopaedic Surgeons (AAOS) recommends with strong evidence based support in favour of the use of flexible intramedullary nailing for treating children age five to eleven years diagnosed with diaphyseal femur fractures. [4, 5] This device exploits a child’s denser bone, rapid healing and ability to remodel during period of bone growth. Here, we establish this axiom by a detailed case presentation, who was successfully treated with flexible intramedullary nailing for diaphyseal fracture of the femur.
